To all whom itmujc mata- Be it known that ll, names WALno srnn, a subject of the King of GreatlBrltain, residing at London, England, have invented a new and useful llniprovernent in Bottle- Cap lteinovers, of which the following is a specification.

ft is well known thatbottles'arefrequently closed hy stopper devices of the kind known as crown seals that is to say devices which consist of a cork or'other packingdisk or ring contained within a metal capsule with a corrugated or criinped lower edge. The capsule is placed on the top of the bottle neck and while the cork or other packing disk or ring is being compressed on to the top of the bottle neck by external pressure, the corrugated or crimped lower edge of the seal is forced radially inward so as to tightly engage the side of the hottle neck.

The object of the present invention is to provide means for unstoppering hottles and the like which have been closed by a capsule the hottom or other edge of which does not afford suficient projection for the engagement therewith of the unstoppering device, and which means is adapted to engage with the outer surface of the capsule or other closing device.

ln the accompanying sheet of drawings Figure 1 is an elevation of an unstoppering device constructed in accordance with my present invention; Fig. 2 is an underside view of Fig. 1; Fig. 3 is a longitudinal section on line X-X of Fig. 2; and Figs. t and 5 are similar views illustrating modifications.

@imilar letters of reference relateto like parts in all the figures of the drawings.

a is a hollow conical nietal fitting adapted to he secured hy screws 6 for example to a counter or other hase or support 0 preferahly in such a position that. its larger and open end is inclined at a suitable angle to the surface of such hase or support as shown in Fig. i. it is ohvious however that the fitting may he varied in general form as may he desired. lit the lower part of the internal surface of the said open end of the fitting one or more projecting surfaces at are provided, slightly inclined hy preference as shown, terminating at their inner ends in more or lesssharp edges e which may he plain, or furnished with serrations or notches ,f own in .53, and may he either at a or crurved correspond;

moreor less with the circular curvature of the neck of the bottle or other receptacle which is shown at g in Fig. 3. Diametrically opposite to the beforementioned sharp edges e is provided an inclined surface It upon the upper part of the internal surface of the open end of'the fitting, which surface may he regarded as a substitute for the central 'hoss, stop or fulcrum of the openers hereinhefore referred to.

The end of the neck of the unstoppered is inserted thelitting l of the capsule which surrounds the neck of the bottle rests upon the sharp inner edge or edges 8 of the lower incline 0?. Upon raising the bottle hy its lower end in the direction of the arrow in Fig. 3, the upper edge of the capsuled neck thereof will he brougtht to hear against the incline It, and any rther movement of the bottle 9 in the same direction will first cause the upper edge of the capsuled end of the neck thereof to be forced inwardly up the incline it, the opposite edge of the said capsuled neck be ing therehy forced on to the sharp serrated or notched edge or edges 6 of the surface 01; and secondly will drag the neck of the bottle out of the capsule, which latter will be free to fall out of the fitting immediately the pressure of the neck of the bottle on the in cline it is released.

some cases instead of a single continu ous or divided sharp edge e, I provide a number of more or less sharp edges, either plain, or errated or notched, upon the surface d' *ig. d) in order to allow for any variation in the diameters of the necks of the hottles, or in the shape of the'shoulders, projections, or grooves formed thereon or therein.

lit will he ohvious that the position in which the heforemention'ed unstoppering de vice is hired, and the positions of the acting surfaces thereof, may be varied according to requirements. lit will he also obvious that the device is equally applicable in cases in which the packing-ring is situated on the enterior of the hottle-neck instead of on the top thereof.

ln Fig. 5 my improved unstoppering device is shown ln this case the hottle bottle 9 to be into the open end of g may he held sta tionary-and the tool he placed in position thereupon as shown in Fig. 5. it will he understood pressure is exerted 1n such a manner that that portion arranged as portable hand tool.

upon the handle 2' in the direction of the arrow, the inclined surface I will force the sharp edge or edges e of the surface (Z into the capsule of the bottle, and continued pressure upon the handle 71 in the same direction as before will drag the capsule off the top of the neck of the bottle g.

Claims:

1. A device for removing stoppers of the kind referred to from bottles and other receptacles consisting of a hollow metal fitting with stopper engaging surfaces positioned diametrically opposite one another, one of said surfaces being provided with an edge adapted to engage the stopper, the other of said surfaces being inclined toward said first mentioned surface whereby as the neck of the bottle or other receptacle is inserted in the device the stopper will be forced by said inclined surface a ainst the edge of said 0,

first mentioned sur ace.

2. A device for removing stoppers of the kind referred to from bottles and other like receptacles which consists of a hollow metal fitting adapted to be fixed to a counter or 25 other base, and furnished with a plurality of projecting surfaces provided with curved edges and an inclined surface positioned opposite to said projecting surfaces.

In testimony whereof I have signed my 30 name to this specification in the presence of two subscribing witnesses.
